Taxes woes continue to mount for the nonprofit organization headed by the Rev. Al Sharpton, The Smoking Gun (TSG) reported.

Citing the latest tax filings from Sharpton's National Action Network (NAN), signed in mid-November and covering 2013, the group continues its ongoing deficit as its delinquent federal tax bill has also ballooned, TSG reported.

The group's federal tax liability rose in 2013 to about $820,000 and is the group's largest debt, TSG said.

Sharpton, the group's CEO and highest-paid employee, had to loan his group $200,000 in personal funds amid the financial woes, TSG said.

The NAN took in $4.9 million in gross receipts from primarily corporate sponsorship, according to its 990 tax form, which is public because of its nonprofit status.

Total expenses for the "Christian, activist, social justice organization" were $5.2 million, leaving a deficit of more than $223,000, TSG said, adding that Sharpton had been in negotiations with the IRS for repayment of back taxes since 2010.

Sharpton's tax problem was outlined by The New York Times in a story from last November. It noted that the civil rights activist "has regularly sidestepped the sorts of obligations most people see as inevitable, like taxes, rent and other bills."

The Times said Sharpton owed more than $4.5 million in state and federal tax liens for both the NAN and himself. Added the Times story: "His National Action Network appears to have been sustained for years by not paying federal payroll taxes on its employees."

Sharpton, as president of the group, earned $241,545 as an annual salary. The second highest paid employee, Michael A. Hardy, who is listed as legal counsel, earned $110,000.
